Probing the Dark Age: From First Generation Objects to Primordial Galaxies

我们利用Cosmo Simulator first探索了宇宙中从第一代天体到原始星系的黑暗时代历史，并在1)第一代天体的形成和连续恒星的形成、2)原始星系的形成和紫外线辐射的辐射转移、3)Lyman α发射体的宇宙学建模、4)紫外线辐射下球状星团的形成、5)原始星系中大质量黑洞的合并等方面取得了重要成果。此外，还提出了一种在六维相空间中直接积分无碰撞玻尔兹曼方程的新方法。此外，在理论成果的基础上，进行了大量的原始星系观测合作，使原始星系的研究取得了重大进展。

We have explored the history of the dark age in the universe from first objects to primordial galaxies by using the Cosmo Simulator FIRST, and then obtained significant results on 1) Formation of first-generation objects and successive star formation, 2) Formation of primordial galaxies and radiative transfer of UV radiation, 3) Cosmological modeling of Lyman alpha emitters, 4) Formation of globular clusters within UV radiation, 5) Merger of massive black holes in primordial galaxies. Besides, a novel method for direct integration of the collisionless Boltzmann equation in Six-dimensional phase space has been developed. In addition, based on the theoretical outcomes, a lot of collaborations on the observations of primeval galaxies have been made, resulting in significant progresses in the study of primordial galaxies.
